Here's my advice to any new chipper.
There's actually plenty of Paulson's out there already. From brand spanking new, to cheap beat-up old used ones.
Advice: Get a game plan of what you want and go for that.
If you don't have a goal of what you want, you'll end up with a mess of all different chips that don't make any sense for a poker game. Ask me how I know.
Do you want to build a cash set or a tourney set? Do you want a mixed set or a set from one casino/theme? Are you going to take the chips, remove the inlay and make your own custom inlays? What colors do you like? What spot patterns do you like? Do you want your chip progression to include "normal" sized 39mm chips and go to "bigger" 43mm sized chips, or do you want to keep everything one size?
Do you want RHC or THC or maybe even house molds?
Leaded or unleaded?
If you don't know the answers, consider getting a sample set (like the one coming up for sale) or buy a few barrels from a few different casinos/themes.
Sample set allow you to see the spot patterns and colors up close. Get a barrel to see how the chips look from the side all stacked up.
And if you have any questions, PM me (when you can). I'll be happy to answer with what I know.
